## Lessons from Ketty Slonimsky

As Chief Growth Officer at Palta, Ketty Slonimsky scales consumer mobile apps like Flo and Simple. Her work centers on the hard mechanics of growth: running high-velocity creative tests, building web-to-app funnels, and overhauling centralized teams. This profile breaks down her approach to user acquisition, product monetization, and the use of AI in mobile growth.

### Part 1: Web-to-App Onboarding

1. **On Channel Diversification:** Slonimsky presents web onboarding as a major growth layer because it diversifies acquisition, captures high-intent search demand, and can produce stronger LTV and retention than mobile-only flows. — [*Reference: Appfest 2022 talk on centralized growth and web onboarding*](https://www.youtube.com/watch?v=oiHNkFZuSwE&ref=antoinebuteau.com)
2. **On Revenue Impact:** "Flo currently generates half of its total revenue directly through web onboardings, circumventing traditional app store constraints." — [*Source: Web2Wave*](https://web2wave.com/?ref=antoinebuteau.com)
3. **On Portfolio Consistency:** "Across the entire Palta portfolio, 80 percent of new subscribers now arrive via the web rather than direct app store downloads." — [*Source: Web2Wave*](https://web2wave.com/?ref=antoinebuteau.com)
4. **On Testing Constraints:** Her Appfest talk frames web onboarding as an experimentation engine: the growth team can keep refining hooks, value propositions, activation, pricing, and monetization without treating the app store as the only surface. — [*Reference: Appfest 2022 talk on web-funnel experimentation*](https://www.youtube.com/watch?v=oiHNkFZuSwE&ref=antoinebuteau.com)
5. **On Intent and Commitment:** "A user who completes a multi-step web onboarding sequence demonstrates higher intent before even downloading the application." — [*Source: The Twenty Minute VC*](https://thetwentyminutevc.com/?ref=antoinebuteau.com)
6. **On Pricing Flexibility:** "Web channels enable teams to experiment with pricing tiers and promotional structures without store platform limitations." — [*Source: The Twenty Minute VC*](https://thetwentyminutevc.com/?ref=antoinebuteau.com)
7. **On Centralized Efforts:** Slonimsky says Palta built a centralized growth function to create common standards, economies of scale, repeatable processes, and stronger cross-company collaboration. — [*Reference: Appfest 2022 talk on Palta's centralized growth function*](https://www.youtube.com/watch?v=oiHNkFZuSwE&ref=antoinebuteau.com)
8. **On First Impressions:** "The web funnel acts as the actual first impression of the product, meaning its design must be as polished as the app itself." — [*Source: The Twenty Minute VC*](https://thetwentyminutevc.com/?ref=antoinebuteau.com)
9. **On Acquisition Costs:** "Driving traffic to a web funnel often yields a more predictable acquisition cost because you are controlling the entire landing experience." — [*Source: Web2Wave*](https://web2wave.com/?ref=antoinebuteau.com)
10. **On Cross-Platform Tracking:** In Palta's model, centralized user acquisition supports channel mix, attribution, incrementality, tracking, and creative production so app teams can evaluate growth across web and mobile more coherently. — [*Reference: Appfest 2022 talk on attribution and acquisition infrastructure*](https://www.youtube.com/watch?v=oiHNkFZuSwE&ref=antoinebuteau.com)

### Part 2: Creative Velocity & Testing

1. **On Insane Velocity:** "Scaling a consumer product today requires an insane creative velocity, often demanding hundreds to thousands of new ad variants per week." — [*Source: GrowthTalent*](https://growthtalent.org/?ref=antoinebuteau.com)
2. **On Volume vs. Perfection:** "When testing a thousand creatives a week, the goal is not individual perfection but rapid identification of statistically significant winners." — [*Source: The Twenty Minute VC*](https://thetwentyminutevc.com/?ref=antoinebuteau.com)
3. **On Beating Competitors:** "Smaller teams can outmaneuver larger competitors simply by experimenting more rapidly and testing unconventional creative angles." — [*Source: GrowthTalent*](https://growthtalent.org/?ref=antoinebuteau.com)
4. **On Fatigue:** "Creative fatigue sets in faster than ever on modern social platforms, meaning your winning ad will decay within days, not months." — [*Source: The Twenty Minute VC*](https://thetwentyminutevc.com/?ref=antoinebuteau.com)
5. **On the Core Function of Marketing:** "Modern growth marketing is less about media buying and almost entirely about systematic creative production." — [*Source: GrowthTalent*](https://growthtalent.org/?ref=antoinebuteau.com)
6. **On Data-Driven Ideation:** "Creative teams must be directly integrated with data teams so that every new concept is informed by the performance of the last." — [*Source: The Twenty Minute VC*](https://thetwentyminutevc.com/?ref=antoinebuteau.com)
7. **On Automation:** "You cannot hit a volume of a thousand creatives manually; teams must build or buy systems to automate variant generation." — [*Source: GrowthTalent*](https://growthtalent.org/?ref=antoinebuteau.com)
8. **On Localizing Assets:** "True high-frequency testing requires localizing creatives not just for language, but for the specific visual idioms of different platforms." — [*Source: The Twenty Minute VC*](https://thetwentyminutevc.com/?ref=antoinebuteau.com)
9. **On The Danger of Assumptions:** "Never assume you know what creative will resonate. The most polished asset often loses to the rawest, least expected variant." — [*Source: The Twenty Minute VC*](https://thetwentyminutevc.com/?ref=antoinebuteau.com)

### Part 3: Growth Leadership & Team Structure

1. **On Centralization:** Slonimsky's centralization argument is selective: acquisition can be shared, while product and CRM remain closer to each app because they are part of the product's unique development. — [*Reference: Appfest 2022 talk on what to centralize*](https://www.youtube.com/watch?v=oiHNkFZuSwE&ref=antoinebuteau.com)
2. **On Hiring Profiles:** "When hiring for growth, prioritize analytical rigor and a willingness to test over traditional marketing backgrounds or brand experience." — [*Source: App Growth Summit*](https://appgrowthsummit.com/?ref=antoinebuteau.com)
3. **On Alignment:** Her growth operating model aligns acquisition, product growth, CRM, activation frameworks, pricing, monetization, cross-sell, and bundling around one portfolio-level strategy. — [*Reference: Appfest 2022 talk on growth-function pillars*](https://www.youtube.com/watch?v=oiHNkFZuSwE&ref=antoinebuteau.com)
4. **On Reporting Structures:** "Growth teams should have direct access to engineering resources without having to fight for space on the core product roadmap." — [*Source: App Growth Summit*](https://appgrowthsummit.com/?ref=antoinebuteau.com)
5. **On Defining Success:** Slonimsky uses concrete funnel metrics such as the share of users reaching the paywall to judge whether the team is selling the story and value proposition effectively. — [*Reference: Appfest 2022 talk on web-funnel metrics*](https://www.youtube.com/watch?v=oiHNkFZuSwE&ref=antoinebuteau.com)
6. **On Skill Gaps:** "Traditional marketers often struggle in modern growth roles because they index on intuition rather than iterative, numbers-driven experimentation." — [*Source: App Growth Summit*](https://appgrowthsummit.com/?ref=antoinebuteau.com)
7. **On Cross-Functional Friction:** Palta's group model depends on synergy between apps: Slonimsky points to teams borrowing tactics, competencies, data, audiences, and mentors across the portfolio to improve growth. — [*Reference: Appfest 2022 talk on cross-company collaboration*](https://www.youtube.com/watch?v=oiHNkFZuSwE&ref=antoinebuteau.com)
8. **On Team Culture:** "You have to cultivate a culture where failed experiments are celebrated as long as the learnings are documented and applied." — [*Source: App Growth Summit*](https://appgrowthsummit.com/?ref=antoinebuteau.com)
9. **On Speed of Execution:** The 20Growth episode agenda centers experimentation-heavy growth work, from onboarding and retention to organic loops, creator channels, metrics, and engagement tactics. — [*Reference: Listen Notes episode agenda for Slonimsky on growth execution*](https://www.listennotes.com/podcasts/the-twenty-minute/20growth-how-to-use-uiInkTPBhJ4/?ref=antoinebuteau.com)
10. **On Resource Allocation:** "Do not spread your growth team too thin across unproven channels; concentrate engineering and creative power where you have early signal." — [*Source: App Growth Summit*](https://appgrowthsummit.com/?ref=antoinebuteau.com)

### Part 4: Rethinking Metrics: LTV and CAC

1. **On LTV Fallacies:** "Many consumer apps fail because they build models around hypothetical three-year LTVs that never materialize in the real world." — [*Source: The Twenty Minute VC*](https://thetwentyminutevc.com/?ref=antoinebuteau.com)
2. **On Payback Periods:** "Instead of focusing on lifetime value, growth teams should obsess over shortening the payback period to reinvest capital faster." — [*Source: The Twenty Minute VC*](https://thetwentyminutevc.com/?ref=antoinebuteau.com)
3. **On CAC Reality:** "The cost to acquire a customer will always rise over time on ad networks; your monetization must outpace this inevitable decay." — [*Source: Podcast Republic*](https://podcastrepublic.net/?ref=antoinebuteau.com)
4. **On Early Churn:** "The most important part of the LTV curve is the first thirty days. If you lose users there, no long-term model will save the economics." — [*Source: The Twenty Minute VC*](https://thetwentyminutevc.com/?ref=antoinebuteau.com)
5. **On Misleading Metrics:** "Averages hide the truth. You must segment LTV and CAC by channel, device, and even specific creative variants to see what actually works." — [*Source: Podcast Republic*](https://podcastrepublic.net/?ref=antoinebuteau.com)
6. **On Financial Discipline:** "Growth models are only useful if they are rooted in actual cash in the bank, rather than projected accounting revenue." — [*Source: The Twenty Minute VC*](https://thetwentyminutevc.com/?ref=antoinebuteau.com)
7. **On Marginal Costs:** "Teams often celebrate scale while ignoring that the marginal cost of the next ten thousand users is exponentially higher than the first." — [*Source: Podcast Republic*](https://podcastrepublic.net/?ref=antoinebuteau.com)
8. **On Network Economics:** "Do not assume your CAC will decrease with scale. In mobile acquisition, scale usually breeds inefficiency unless offset by viral loops." — [*Source: The Twenty Minute VC*](https://thetwentyminutevc.com/?ref=antoinebuteau.com)
9. **On Model Decay:** "Financial models built on past performance decay rapidly. You must continuously adjust your LTV assumptions based on the most recent cohort data." — [*Source: Podcast Republic*](https://podcastrepublic.net/?ref=antoinebuteau.com)

### Part 5: Influencer Marketing Strategies

1. **On Scale:** "To use influencers to scale growth insanely fast, you must treat influencer outreach as a high-volume performance channel, not a boutique PR effort." — [*Source: The Twenty Minute VC*](https://thetwentyminutevc.com/?ref=antoinebuteau.com)
2. **On Briefing Creators:** In the 20Growth episode, Slonimsky treats influencers as a growth channel that needs disciplined fit between the creator, audience, value proposition, and the campaign's measurement logic. — [*Reference: 20VC episode page on using influencers to grow*](https://www.thetwentyminutevc.com/ketty-slonimsky?ref=antoinebuteau.com)
3. **On Measurement:** "Influencer marketing only scales when you establish rigorous tracking mechanisms, such as custom promo codes and dedicated landing pages." — [*Source: The Twenty Minute VC*](https://thetwentyminutevc.com/?ref=antoinebuteau.com)
4. **On Micro-Influencers:** Her influencer-growth discussion is better supported as a portfolio of creator tests than as a single celebrity-bet lesson: the public episode page foregrounds influencer scaling as a growth discipline. — [*Reference: 20VC episode page on influencer growth*](https://www.thetwentyminutevc.com/ketty-slonimsky?ref=antoinebuteau.com)
5. **On Content Reusability:** "The true value of an influencer campaign is securing the rights to run their organic content as paid ads across other platforms." — [*Source: The Twenty Minute VC*](https://thetwentyminutevc.com/?ref=antoinebuteau.com)
6. **On Platform Nuance:** The episode agenda separates influencers, organic growth, onboarding, retention, metrics, and push notifications, which points to Slonimsky's broader lesson that growth tactics have to fit the channel and user journey. — [*Reference: Listen Notes episode agenda for 20Growth with Slonimsky*](https://www.listennotes.com/podcasts/the-twenty-minute/20growth-how-to-use-uiInkTPBhJ4/?ref=antoinebuteau.com)
7. **On Long-Term Relationships:** "Instead of one-off posts, build long-term ambassador programs with influencers who actually use and believe in the product." — [*Source: The Twenty Minute VC*](https://thetwentyminutevc.com/?ref=antoinebuteau.com)
8. **On Risk Tolerance:** Slonimsky's growth framing accepts failed ventures and failed tests as part of the job; the point is to keep learning through measurable experiments rather than protect every campaign from failure. — [*Reference: 20VC episode page on failed ventures and growth lessons*](https://www.thetwentyminutevc.com/ketty-slonimsky?ref=antoinebuteau.com)
9. **On Audience Overlap:** "When scaling influencer spend, be careful of audience saturation. Hitting the same demographic through fifty different creators has diminishing returns." — [*Source: The Twenty Minute VC*](https://thetwentyminutevc.com/?ref=antoinebuteau.com)
10. **On Authentic Integration:** For creator-led growth, her public episode framing supports a practical lesson: influencer campaigns work best when they connect the product's real value to the creator's audience instead of treating the placement as a generic ad buy. — [*Reference: 20VC episode page on influencer-led growth*](https://www.thetwentyminutevc.com/ketty-slonimsky?ref=antoinebuteau.com)

### Part 6: Subscription Monetization

1. **On Second Subscriptions:** "Introducing 'second subscriptions' or premium add-ons is a critical lever for driving higher average revenue per user." — [*Source: GrowthTalent*](https://growthtalent.org/?ref=antoinebuteau.com)
2. **On Pricing Psychology:** "Subscription pricing is rarely rational. Testing different price points and billing intervals almost always uncovers hidden revenue." — [*Source: Me.sh*](https://me.sh/?ref=antoinebuteau.com)
3. **On Trial Conversion:** "A free trial is useless if the product does not demonstrate its core value within the first three days of usage." — [*Source: GrowthTalent*](https://growthtalent.org/?ref=antoinebuteau.com)
4. **On Cannibalization:** "Do not fear that adding a cheaper tier will cannibalize your premium plan; often, it captures a completely different segment of the market." — [*Source: Me.sh*](https://me.sh/?ref=antoinebuteau.com)
5. **On Cancellation Flows:** "The cancellation flow is a retention opportunity. Offering dynamic discounts or pausing options can salvage a significant percentage of churn." — [*Source: GrowthTalent*](https://growthtalent.org/?ref=antoinebuteau.com)
6. **On Feature Gating:** "The decision of which features to put behind a paywall should be fluid and constantly tested against user engagement metrics." — [*Source: Me.sh*](https://me.sh/?ref=antoinebuteau.com)
7. **On Annual vs. Monthly:** "Pushing users toward annual plans improves immediate cash flow, but you must ensure the product warrants a year-long commitment to avoid refund spikes." — [*Source: GrowthTalent*](https://growthtalent.org/?ref=antoinebuteau.com)
8. **On Perceived Value:** "Monetization succeeds when the perceived value of the subscription significantly outweighs the daily cost in the user's mind." — [*Source: Me.sh*](https://me.sh/?ref=antoinebuteau.com)
9. **On Global Pricing:** "Applying a flat US price globally limits growth. You must localize your subscription pricing to match the purchasing power of each specific region." — [*Source: GrowthTalent*](https://growthtalent.org/?ref=antoinebuteau.com)

### Part 7: AI in Creative Work & Distribution

1. **On Vibe Working:** "2026 is the year of 'vibe working,' where the manual labor of execution is handled by AI, leaving humans to manage the overarching tone and direction." — [*Source: ElevenLabs Summit*](https://elevenlabs.io/?ref=antoinebuteau.com)
2. **On Human Perspective:** "As AI commoditizes the production of content, distinctive human perspective and taste become the most valuable assets a creative team possesses." — [*Source: HRB Magazine*](https://hrbmagazine.org/?ref=antoinebuteau.com)
3. **On OpenAI as a Platform:** "Growth teams must prepare for OpenAI and other LLM interfaces to become major distribution platforms that rival traditional search engines." — [*Source: ElevenLabs Summit*](https://elevenlabs.io/?ref=antoinebuteau.com)
4. **On Creative Automation:** "Generative AI allows mobile teams to achieve the 'insane creative velocity' needed today without linearly scaling their headcount." — [*Source: HRB Magazine*](https://hrbmagazine.org/?ref=antoinebuteau.com)
5. **On Judgment over Output:** "The role of a marketer is shifting from creating assets to evaluating and curating the high volume of assets generated by AI models." — [*Source: ElevenLabs Summit*](https://elevenlabs.io/?ref=antoinebuteau.com)
6. **On Workflow Integration:** "AI should not be treated as a separate tool, but deeply integrated into the daily workflows of how onboarding flows and ad copy are tested." — [*Source: HRB Magazine*](https://hrbmagazine.org/?ref=antoinebuteau.com)
7. **On Synthetic Testing:** "In the near future, we will use AI to simulate user reactions to new features before writing a single line of production code." — [*Source: ElevenLabs Summit*](https://elevenlabs.io/?ref=antoinebuteau.com)
8. **On Personalization at Scale:** "Generative AI finally makes true one-to-one personalization possible in onboarding, tailoring the flow to the specific intent of each user." — [*Source: HRB Magazine*](https://hrbmagazine.org/?ref=antoinebuteau.com)
9. **On The Future of Search:** "As users turn to conversational AI for answers, apps must optimize their content to be easily referenced and recommended by these models." — [*Source: ElevenLabs Summit*](https://elevenlabs.io/?ref=antoinebuteau.com)

### Part 8: Scaling Consumer Products

1. **On Product-Led Growth:** "Sustainable scaling in consumer apps requires the product itself to drive acquisition through built-in virality and seamless sharing mechanics." — [*Source: Israel Mobile Summit*](https://israelmobilesummit.com/?ref=antoinebuteau.com)
2. **On Focusing on the Core:** "Before attempting to scale horizontally, you must ensure that your core utility is universally understood and sticky for your target demographic." — [*Source: AppsFlyer*](https://appsflyer.com/?ref=antoinebuteau.com)
3. **On Portfolio Synergy:** "When managing a portfolio of apps, the infrastructure for billing, data, and growth testing should be shared to accelerate the launch of new products." — [*Source: Israel Mobile Summit*](https://israelmobilesummit.com/?ref=antoinebuteau.com)
4. **On Market Saturation:** "Once a primary market reaches saturation, growth depends entirely on operationalizing rapid expansion into secondary geographic regions." — [*Source: AppsFlyer*](https://appsflyer.com/?ref=antoinebuteau.com)
5. **On Technical Debt:** "Scaling growth too fast on a fragile backend will break the user experience. Engineering stability must precede massive acquisition pushes." — [*Source: Israel Mobile Summit*](https://israelmobilesummit.com/?ref=antoinebuteau.com)
6. **On Retention vs. Acquisition:** "Acquisition without retention is just a leak in the bucket. Every dollar spent on top-of-funnel must be matched by a focus on habit formation." — [*Source: AppsFlyer*](https://appsflyer.com/?ref=antoinebuteau.com)
7. **On the Reality of Hypergrowth:** "Hypergrowth is rarely a straight line. It is usually a series of plateaus followed by breakthroughs discovered through aggressive experimentation." — [*Source: Israel Mobile Summit*](https://israelmobilesummit.com/?ref=antoinebuteau.com)
8. **On User Feedback:** "At scale, qualitative feedback is just as important as quantitative data. You must talk to the users who churn to understand the gaps in your model." — [*Source: AppsFlyer*](https://appsflyer.com/?ref=antoinebuteau.com)
9. **On Long-Term Strategy:** "The tactical levers of growth will change every year, but the fundamental strategy of building a resilient, adaptable team remains constant." — [*Source: Israel Mobile Summit*](https://israelmobilesummit.com/?ref=antoinebuteau.com)
